ATI 2007 or ATI 1807


I am contemplating on one of the above. I have a small listening HT room
10ft x 10ft and I am presently using a Yamaha AVR RXA-3010 in a 9.2 set up.
I am planning to hold on to the Yamaha for now and use it as a pre-amp and buy a ATI 1807 or a 2007 for better dynamics and so on..
It their a huge improvement in sound quality with the ATI 2007 to justify the extra cost over the 1807?
I would be most grateful for any advice please.

It depends on the efficiency of your speakers and how hard they are to drive. If your speakers are fairly easy to drive, especially in that small of a room, the 1807 will be just fine. However, if I may say so, the size of your room seems small for a full 9.2 set-up. Additionally, you will have acoustical issues having basically a square room.

I do not remember all the details, but at least the 3007 requires a 20 amp circuit. If I remember correctly the 2007 comes with a 20 amp plug, although I think it does not require a 20 amp circuit like the 3007. Just something to think about.

I run a 2006 with an old Yamaha receiver and am very pleased with it. However, I do have a separate amp for my mains, which are part of a 2 channel hybrid system. The ATI replaced a B&K 200.7 and I find the ATI a much smoother sound.
